I like the original Ripped 1000 but it is a LONG workout, over an hour, but is chaptered so you can skip a section if you need to shave off some time. I like Hardcore 1000 and find it more difficult but shorter, the cardio segments are longer in HardCore 1000.
Don't like Get Extremely Ripped 1000 at all and find the cover photo of Jari disturbing. Can't get into an instructor's appearance and I won't other then to say she looks scary skinny on that cover.
Guess that little to rate these for you.....I would say GER HardCore 1000 is the most intense
